Outsole having double structure transparency for shoes and manufacturing method

The present invention relates to a dual-structure shoe outsole having a transparent window and a method for manufacturing the same. More specifically, it satisfies the intrinsic function of the outsole that prevents slipping while walking and improves abrasion resistance. In addition, the sole of the shoe is transparent, and gold or silver pearls are embedded in the inside, and the sole is made to be flashed through the transparent window so that it can be composed more beautifully and highly structured. It is about a method.

In general, a shoe sole includes a midsole on which an insole is placed on an upper surface thereof, and an outsole adhered to a lower portion of the midsole.

The midsole prevents the shape of the shoe from being deformed, and provides a cushion effect. The insole protects the sole of the sole where the sole is directly contacted by the wearer, and the outsole prevents slipping when walking. It is to function to give abrasion resistance. In addition, the outsole is configured to configure the appearance of the shoe together with the upper.

Conventional outsole is composed of a single layer molded from a material containing carbon as a reinforcing agent in addition to the rubber and additives as the main material in order to prevent slipping and impart wear resistance when walking.

However, such a conventional outsole merely provides non-slip and wear resistance, so that the impact on the wearer's foot through the sole of the foot during walking is entirely dependent on the midsole, which does not sufficiently alleviate the impact on the foot. have.

In addition, since the conventional outsole is composed of a single layer that provides anti-slip and wear resistance, there is a problem in that the appearance of the shoe together with the upper is monotonous and the maturity of the shoe is poor.

In other words, shoes worn daily for the purpose of exercise, walking, work, etc. have an outer cover (or upper) shaped to cover the wearer's feet and insoles (or insoles, insoles, insoles) and bottoms located inside the outer cover. The bottom plate consists of a midsole (or midsole) and a softer outsole (or outsole) made of soft resilient material. Such shoes are completed by adhering the bottom surface of the bottom plate and the top surface of the midsole in a state where the bottom plate and the outer shell are attached and fixed.

More specifically, the outer shell is designed to protect the foot, to hold the foot stable, and to be mainly considered to give the aesthetic and luxury of the aesthetic point, and the shoe midsole contributes to the stability of the foot and acts as a shock absorber or cushion. In general, the structure of the midsole will determine the weight and price of the shoe. Outsoles, on the other hand, provide durability, grip and flexibility for foot comfort. As the first layer of natural wear in daily use, it acts like a tire in a car and various patterns of the sole bottom are devised for maximum support and best performance.
